Purpose
Dams are typically designed to serve as food protection, provide water for irrigation, human and animal
consumption, and harness hydropower. Despite these benefts, dam operations can have adverse
effects on in-reservoir and downstream water temperature regimes, biogeochemical cycling and
aquatic ecosystems. We present a water quality dataset of water withdrawal scenarios generated after
implementing the 2D hydrodynamic and water quality model, CE-QUAL-W2. This dataset intends to
facilitate a broader investigation of in-reservoir nutrient dynamics under dam operations, and to extend
the understanding of reservoir nutrient dynamics globally.
Abstract
The Lake Diefenbaker CE-QUAL-W2 model has 87 horizontal segments starting at Saskatchewan highway 4 at the upstream extending to the Gardiner Dam and the Qu'Appelle Dam at downstream, and one-meter vertical layers with a maximum of 60 layers at the deepest point near the Gardiner Dam. Gardiner dam outflow is either via metalimnetic withdrawal through hydroelectric turbines or via a spillway during brief high flow periods. The current operational withdrawal depth of approximately 34m was altered in the model according to six extraction depth scenarios (5, 15, 25, 35, 45, and 55 m) to determine impacts on nutrient distribution and concentrations within the reservoir. The model is calibrated for water temperature, PO4, organic P, TN , NH4, NO3, organic N, and dissolved oxygen.
